ERROR! The server quit without updating PID file (/usr/local/mysql/data/localhost.localdomain.pid).

这个错误是在启动MySQL时出现的，它指出服务器在更新PID文件时退出了。根据引用\[1\]、\[2\]和\[3\]提供的解决方法，可能的原因是数据目录或PID文件没有正确的权限。解决方法是给予相应的权限。你可以尝试执行以下命令来解决问题：

1. 给予数据目录权限：执行命令`sudo chmod -R 777 /usr/local/mysql/data/`。
2. 给予PID文件权限：执行命令`chown -R mysql:mysql /var/data`和`chmod -R 755 /usr/local/mysql/data`。
3. 如果以上方法不起作用，你可以尝试执行命令`sudo chown -R _mysql /usr/local/var/mysql`。

执行完这些命令后，重新启动MySQL，应该能够解决这个问题。
